Description: ------------ perhaps related to #12678. gethostbyname() gives the IPv6 hostname back instead if the IPv6 ip. In IPv4 everything works fine. Note: IPs and hostnames in the following snipplets are replaced with example entries. It was tested with working IPs both in IPv4 and IPv6. Reproduce code: --------------- $client_ip = $_SERVER["REMOTE_ADDR"]; $client_hostname = gethostbyaddr($_SERVER["REMOTE_ADDR"]); $client_hostname2ip = gethostbyname(gethostbyaddr($_SERVER["REMOTE_ADDR"])); echo $client_ip."->".$client_hostname."->".$client_hostname2ip; Expected result: ---------------- In IPv4: 10.11.12.13->server.domain.de->10.11.12.13 In IPv6: 3ffe:1::1->server.ipv6.domain.de->3ffe:1::1 Actual result: -------------- In IPv4 (working fine): 10.11.12.13->server.domain.de->10.11.12.13 In IPv6 (last output broken): 3ffe:1::1->server.ipv6.domain.de->server.ipv6.domain.de -- Edit bug report at http://bugs.php.net/?id=33170&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33170&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33170&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33170&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33170&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33170&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33170&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33170&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33170&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33170&r=support Expected behavior: http://bugs.php.net/fix.php?id=33170&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33170&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33170&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33170&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33170&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33170&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33170&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33170&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33170&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33170&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33170&r=mysqlcfg
